Throughout my career, I have successfully scaled platforms to support 3 million+ users and 60 million+ monthly transactions while optimizing infrastructure costs through serverless transitions. I combine deep backend engineering expertise with strategic leadership, mentoring teams and guiding product-driven AI innovation to deliver reliable, production-grade systems.
